Intelligent DC-DC chargers

BMPRO’s ProBoost25 is a DC-DC battery charger that allows you to charge a secondary battery using solar panels and/or a towing vehicle’s 12V electrical system.

The ProBoost25 utilises solar and auxiliary inputs to produce a maximum of 40A which ensures there is a consistent charge to your battery.

Compatible with both lead-acid and lithium LiFePO4 batteries, the high power density design of the ProBoost25 provides efficiency of up to 93%.

The ProBoost25 has an ultra-thin design, making it suitable for installation in small spaces, and is resilient to shaking, as well as wet, dusty or muddy environments.

A range of protective features built into the ProBoost25, such as overtemperature, overvoltage and undervoltage protection, will guard your charging capacity.

Features

• Dual input MPPT solar/aux (alternator)
• Multi-battery chemistry selector
• IP56 rating – resistant to dust, water & shock damage
• Maintains a 100% state of charge of auxiliary batteries
• Suitable for under-bonnet installation

*The ProBoost DC-DC Charger is designed to work as a standalone product.

To use this with a BMPRO Power Management System, such as the BatteryPlus35-II or the J35, you will need to connect it through a BC300 External Shunt.
